NeweggFlash offers the refurbished Asus 802.11n Wireless Dual Band Gigabit Router, model no. RT-N66R, for $49.99 with free shipping. That's $53 under the lowest total price we could find for a new unit, although we saw a refurb for $5 less two weeks ago. This router features data transfer rates of up to 900Mbps, USB, four LAN ports, and DD-WRT open source support.

A 90-day warranty applies, although it's not clear who backs it.
